So I bought my first new car a few weeks ago. It is a Volkswagon Jetta TDI model, which means it's diesel. I put 1,200 miles on it so far. My average MPG is 43.8. I wanted a stick but the dealer swore that they don't get better mileage anymore, that technology has changed and they are roughly equal in MPG. My first reaction to the high MPG is 1) I am never, ever going back even with $2.00/gallon gas, 2) We are all talking about hybrid, electric, when the volkswagon diesel is a very good solution right here right now that works. Some other things that surprised me was no emissions testing is necessary (at least in Pennsylvania where I live) and that oil changes are every year or 10,000 miles, whichever comes first. Both are nice selling points although very minor in the scope of things.
